7 HEAT REGENERATOR.

. Application fiiea'nn 'zaf This invention relates to heat recuperatorsor regenerators, and has particular reference 7 to those formed offirebrick or otherrefractori material. V 7

Heretofore, regenerative furnaces have been formed of a plurality ofvariously shaped elements which were expensive and diflicult to make andrequired specially skilled worlnnento erect because of the in ingelements that. can be'readily setup by anyone s tilled in the laying ofbrick or ma sonry, and in such a manner that weight is distributedamongthe elements instead of being borne by a fewelements. v j

A further object. of this invention'is to provide a regeneratorconstruction such that the joints of the special elements forming thecircuits for the currents of gas or, liquid shall be impervious to theSZUHQQ GELCh element co acting with the adjoining interlocking elementsto formcollinear tubular passageways having only transverse joints, theseveral passage-ways for one substance being at right angles to thepassage-ways ofthe other substance so as to form a cross-current heat interchanger.

Other objects and advantages ofthis in vention will become apparent froma'description of a preferred embodiment thereof such as is illustratedin the accompanying drawings in which like reference charactersdesignate like parts in the several views.

In the drawings:

Figure 1 is aperspective view of the special element of which theregenerator is constructed.

Fig. 2 is an elevation of the regeneratorthus constructed, being shownpartly in section as seen along line 22 of Fig. 3.

Fig. 3, which is a sectional plan view of the regenerator as seen alongthe line 33 of Fig. 2.

Referring to Fig. 1, numeral 1 designates register with passa eways 3.ot each row equal to the width of t'enons 2, plus the negl 192s.v SerialNo. 125,563.

the symmet-rical regenerator element which is substantially rectangularin form and is providedat two opposite sides with transverse tenons 2,parallel to the common plane of which are passage-ways 3 disposed ateachside of passage-way 4, which is formed in the common plane oftenons2and at right angles to the direction of passage-ways 3.

As" illustrated 111 F 1g; 2, the regenerator is adapted to be used witha furnace. of'some kind, the hot gaseous products of combustion.

thereof passing through horizontal passageways 4 and? on. their waytothe smokestack, and. the cold air, blast passing vertical- 1 y downwardthroughpassage ways 3, whereby the air isheatedf by contact withthe hotelements and passesout below as a hot blast to the furnacecomb-ustionchamber or utilized to other purposes. Simultaneously with the heatingof the air blast, the flue gases are cooled before passing "into thestack. Fig. 3 illustrates-the arrangement of the elements as seen inplan section, the flue gases passing through horizontal passage-ways 4and 4 and the airblastpassing through vertical passage-waysfi.

In constructing the regeneratonthe foundation is preferably providedwith a not blast duct 6 havingopenin s which are adapted to registerwith ver ical passageways 3 formed by interlocking elements 1.

asshown in Fig. 2. Finishing slabs 8 may be utilized at the top andbase,fand which are also provided with openings adapted to The elementsare spaced apartby distances gible space for mortar, and the elements ofthe second row are likewise spaced apart by the width of tcnons 2 whichare fitted into the spaces between the elements of the next lower row,etc. Thus each successive row of elements is displaced laterallyrelative to the next adjoining rows, so that each element centers withthe space between theelements of the next adjoining rows. The projectingportions of the end elements of alternate rows are set in side walls 9as shown in igs. 2

and 3.

It vwill be evident from the above descrip-;

tion that a simple and eflicient regenerator for exchanging heat or coldbetween gases, liquids, or gases and liquids, may be readily constructedby utilizing a plurality of the specially-shaped interlocking elementsor bricks il i ustrated in Fig. 1. While the regenerator of thisinvention has been described as a flue'gas-heat exchanger orinterchanger, it is to be understood that it may be used for otherpurposes, that the heating or cooling medium may be alternatively passedthrough the vertical or horizontal tubes and in either direction, andthat changes may be freely made in form and detail without departingfrom the spirit of this invention within the scope of the appendedclaims.

What is claimed is:

1. A substantially cubical regenerator element symmetrical about eachcentral plane, tenons disposed upon two opposite surfaces in a centralplane, passage-ways through said element in the central plane of saidtenons, and other passage-ways disposed in planes parallel to thecentral plane of said tenons.

2. An element for regenerator construction having tenons formed upon twoof its opposite faces,'passage-ways formed through said element in thecommon plane of said tenons, and other passage-ways formed through saidelement in planes parallel to the common plane of said tenons and at anangle to the first-named passage-ways.

' 3. A regenerator element having substantially rectangular surfaces,transverse tenons disposed centrally across two of its oppositesurfaces, a passage-way formed through said element in the common planeof said tenons, and other passage-ways formed through said element inplanes parallel to the common plane of said tenons and disposed at eachside of and passing at right angles to the first-named passage-way.

4. A regenerator element having substantially rectangular surfaces,rectangular tenons projecting transversely from two opposite surfaces, apassage-way formed through said element in the common plane of andhaving a rectangular cross-section substantially equal to the surface ofsaid tenons, and

other passage-waysformed through said elein the next adjoining elementsto groups of relatively rectangular passage-' ways through the compositestructure, each opposite faces, one of the edges of two adj acentelements being disposed at each side of one of said tenons whereby saidtwo adjacent elements .are spaced apart by the widthof said tenons toform passage-ways between said elements parallel to one of saidfirst-named groups of passageways, each passage-way in said elementsregistering with acorresponding passage-way in the next adjoiningelement, and each of said passage-ways formed between said elementsregistering with the corresponding passage-way formed between the nextadjoining elements.

6. A regenerator comprising a plurality of interlocking like elements toform two groups of continuous passage-ways at right angles, saidelements being spaced apart in rows, alternate rows of said elementsbeing displaced laterally so that eachelement is centered with thespaces between elements of the next adjoining rows to form apassage-way, each of said elements being provided with a tenon toproject into said spaces, one of said groups of passage-ways registeringin vertical rows, and the other of said groups of passage-waysregistering in horizontal rows, the passage-ways formed betweensaidelements being parallel to said horizontal rows or passage-ways.

7 A regenerator comprising a plurallty of interlocking like elements,each element being symmetrical about each central planethereof, twogroups of passage-ways through each element at right angles, tenons upontwo opposite sides of. and in a central plane of each element, saidelements superimposed rows, alternate rows being displaced so that thetenons thereof project into the spaces of the next adjoining rows,whereby each passage-way in each of said elements registers with acorresponding passage-way form two groups of continuous passage-ways atright angles through the composite structure.

In testimony whereof I affix my signature.
